According to CSA2 the country has a potential to produce about 50,790,578 kilogram of honey per year. However, the majority of honey (47,352,624kilogram) that accounts about 93.2% was harvested from traditional beehive type. The honey produced from the traditional hive is generally poor both in quantity and quality. The prevailing production constraints in the beekeeping subsector in Ethiopia are lack of knowledge, shortage of skilled man power, shortage of bee equipments, pests and predators, agrochemicals, shortage of bee forage and lack of research extension.3 Bernard4 argued that livelihoods of the farmers engaged in beekeeping activity rely on natural capital where bees, flowering plants and water. Bees feed on the nectar and pollen from flowers, the nectar is eventually converted into honey. Gums and resins are collected from plants, which again act as habitat for nesting places. Bees are a natural asset accessible in the wild. Honey bees collect honey ingredients from different sources like wild; wastelands and even land-mined areas all have value for beekeeping. Beekeeping is therefore, possible in arid areas as a livelihood resilient strategy. It provides an excellent bonus crop in addition to, but not a substitute to other crops. In addition to this, Beekeeping is an important agricultural sector that utilizes natural nectar and pollen for production of honey, wax and other hive products that have a great contribution for the income of smallholder farmers.5 Most of local beehives are hanged over high trees. Honey production from honeybees are very low with an average of 5-6kg per hive per year, while from the improved one average of 15-20 kg even more is possible. Honey and beeswax are collected after rainy season; starting from October to December. In the South and Eastern parts, in addition to the main, there is minor harvesting period during May-June. According to CSA, the major honey and beeswax producing regions in Ethiopia are Oromia (41%), SNNPR (22%), Amhara (21%) and Tigray (5%).6 However, the country is suffering from the ecological degradation of its natural resources and this means the basis for any honey production is threatened and affected. In many regions of the country, beekeeping is considered as one of the income-generating activities for resource-poor farmers including women, youth and the unemployed sectors of the community.7 Even though Basketo Special Woreda1 is potential for beekeeping activity, the farmers did not get adequate benefit from beekeeping subsector because of the traditional method of beekeeping system. This system is mainly characterized by low quality and yield of honey. Even though, the agro ecology condition of the area is appropriate for beekeeping operation, there is no research conducted so for to determine the honey production system and constraints. Moreover, identifying the existing beekeeping p","PeriodicalId":131171,"journal":{"name":"Horticulture International Journal ","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122971303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, generally 50% of N and 90% of P from applied inorganic fertilizers are fixed up in soils and run off, and ultimately it releases into atmosphere and water sources, which contribute for greenhouse gas generation, eutrophication and soil salinization.1,2 Application of excessive P induce cadmium in soil that come to food chains.3 Moreover nitrogen application increase nitrates in ground water which are finally responsible for N-nitroso compounds and ultimately often linked with fatal methemoglobinemia.4 To minimize these problems the relevant researchers have been trying to develop sustainable safe and environmental friendly technologies that will help to minimize usages of chemical fertilizers for crop production.

Application of Trichoderma fungi ensures the favorable environment for growing and proliferation of abundant healthy roots and simultaneously plant derived sucrose which is an important resource provided by the Trichoderma spp. Cells.17 Thus plants become benefited from this relationship through increased root and shoot growth and increased macroand micronutrient uptake. Therefore, Trichoderma spp. are being treated as growth promoting (bioorganic fertilizer) as well as pathogen control agent (mycofungicide) and their application may lower the production cost of crops along with conserving congenial environment.

Whitaker & Davis,2 Munger & Robinson,3 Robinson & Decker-Walters4 also contributed to Naudins1 classification which remained a basis for melon intraspecific classification with amendments being brought today. These taxonomic studies results to the 7 intra-specific groups of melons known present: agrestis (wild melon), cantalupensis (sweet melon), inodorus (winter melon), flexuosus (snake melon or snake cucumber), conomon (pickling melon), dudaim (mango melon or pomegranate melon) and momordica (snap melon). Africa is considered to be the centre of origin for melon because of the frequent occurrence of wild species of Cucumis with the same basic chromosome number n=12.5 The secondary center of origin of melon is in Turkey, Syria, Iran, Afganistan, India, Turkmenistan, Tadjikistan and Uzbeskistan.China, Korea, Portugal and Spain were also referred as the secondary centres of diversity for these species. Whitaker & Bemis6 also indicated that C. melo are found only in eastern tropical Africa south of the Sahara. In addition to the results, Pitrat et al.7 reported that wild types are commonly found in the Sudano-Sahelian area Furthermore the secondary centre of diversity stretch from Asia the Mediterran to Japan. Cucumis melo, which came in many different forms and uses, is one of the important horticultural crops worldwide and plays an important role in international trade. The immature and mature melon fruits are used as dessert and vegetables.5 Melon seeds are also eaten after being slightly roasted, and is also used to produce edible oils. Pest and different agents, such as bacteria, fungi and viruses are known to provoke diseases and great losses in melons. Their distribution and impact on melon plants vary around the world. Fusarium wilt, powdery mildew, Alternaria leaf blight and gummy stem blight are among the important fungal diseases known. Lecoq et al.8 discussed that some viral diseases that cause economic losses globally are Cucumber Mosaic Virus (CMV), Papaya Ring Spot Virus (PRSV), Watermelon Mosaic Virus 2 (WMV 2), Zucchini Yellow Mosaic Virus (ZYMV), Cucurbit Aphid-Borne Yellows Virus (CABYV), Squash Mosaic Virus (SqMV) and Watermelon Chlorotic Stunt Virus (WCSV).Pests such as the white fly, aphids, leaf miner and the fruit flyare different insect species known to infest melons. Damages caused by insect pest are either direct through insect feeding or indirect through transmission of viral diseases. White flies (Bemisia tabaci) known to transmit Geminiviruses as WCSV,9 while aphids are known to transmit both Luteo viruses as CABYV10 and Potyviruses as ZYMV.4 Leaf miners (Liriomyza spp.) caused damageon melons through feeding punctures while it larva bores leaf tissues.10 The melon fruit fly (Dacus spp.) also causes severe damage during oviposition of female fly in immature melon fruits.4","PeriodicalId":131171,"journal":{"name":"Horticulture International Journal ","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131926162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
